SO good! I was visiting my boyfriend that was living in Arizona, and he insisted on bringing me to Portillo's, he knew I was going to love it! I had never heard of it before because I from Montreal. I had hands down one of the best beef sandwiches in my life. It had these tasty hot peppers too. I enjoyed the crinkle cut fries as well, very yummy (but very fattening!). Definitely a must have if you are around!
